[object Object]
STRUCTURAL: High government dependence (85) and regulatory density (90) due to MBS market's ties to federal housing policy and 8 impacting finance bills. EVIDENTIARY: Single executive branch holding (`get_executive_branch_exposure.by_ticker[0].positions`: 1) and active trading by one congressperson (7 trades) are isolated signals against zero lobbying, donations, or insider buys (`get_corporate_insider_signal.total_buys`: 0). Net: High structural risk is not counterbalanced by coordinated evidentiary support.
